Specification of Letters Patent.

Patented May 16, 1916.

Application filed October 15, 1915. Serial No. 56,078.

To all whom it may concern:

Be it known that I, RICHARD J. SALES, a citizen of the United States,residing at Delphi, in the county of Carroll and State of Indiana, haveinvented new and useful Improvements in renches, of which the followingis a specification.

This invention relates to improvements in wrenches and has relation'moreparticularly to that class thereunder known as the slidable jaw type.

The primary object of the invention is the provision of a device of theabove stated character wherein means are provided for effecting a speedyadjustment of the movable jaw with respect to the stationary jaw, andfor positively holding the movable jaw at the desired point ofadjustment and pre venting any accidental slipping of the same duringthe turning action of the Wrench.

A still further object of the invention is the provision of a device ofthe above stated character wherein means are employed for holding themovable jaw in its desired adjusted position and embodying a toothedstationary handle and a pivotally connected toothed handle, and meansengaging with the pivotal handle for holding the teeth thereof out ofengagement with the teeth of the stationary handle upon inactiveposition of the wrench.

With the above and other the invention consists in the novel features,details of construction and combination of parts which will hereinafterbe more fully set forth, illustrated in the accompanying drawings andpointed out in the appended claims.

Figure 1 is a side elevation of the wrench illustrating the handleportions thereof in open position. Fig. 2 is a side elevation of themovable jaw and its parts in dissembled position. Fig. 3 is a sideelevation of the stationary jaw and its parts in dissembled position.Fig. 4 is a detail longitudinal section of the stationary handle.

Referring more particularly to the drawing by way of referencecharacters, 5 denotes my improved wrench comprising a shank 6 providedat its free end with a stationary jaw 1. The free end of the shank 6 hasits lower surface for a portion of the shank, beveled upwardly as at 8in a direction toward the free terminal 9 thereof, the

objects in view,

purpose of which is clearly set forth as the description of theinvention is proceeded with. The shank is also provided with an opening10. Fastened to the free end of the shank is a stationary handle 11having an inner toothed surface 12. The stationary handle 11 is formedwith an elongated opening 13 opening out through the inner end ofthehandle and having-its bottom wall inclined upwardly and rearwardly as at14: to agree with the inclination of the inclined or beveled portion 8of the shank, and when the stationary handle is fixedly secured to theshank by means of the threaded pin 14 passing through the registeringopenings 10 and 16 respectively, the inclined portion 8 of the shanktightly binds or wedges against the bevel wall 14 of the opening 13 andthereby obviates the necessity of employing additional fastening means,and furthermore prevents any accidental pivotal movement of thestationary handle 11 during the clamping action of the wrench with a nutor the like to be adjusted.

Mounted for sliding movement upon the shank 6 is a movable jaw 16 havinga rearwardly extending reduced shank 17 formed medially of its lengthwith opposed laterally projecting lugs 18, said lugs serving as grips topermit of the jaw 16 being slidably adjusted on the shank 6 as theoccasion may demand. The shank neoted with its free end a movable handle19, through the medium of a pintle 20, passing through the aperture 21of the spaced ears 22 and through the opening 23 of said shank. Thelower surface of the shank 17 of the movable jaw is inclined upwardlyand rearwardly as at 24 for accommodating the attachment to the shank 17of a leaf spring 25. The leaf spring 25 is attached to the inclinedportion 24 of the shank 17 through the medium of a fastening means suchas a rivet or the like length greater than the length of the 1Il--clined portion 24 to permit a portion there of to extend beyond the freeend 27 of the shank 17, to permit of the spring 25 seating within therecess 28 of the pivotal jaw thereby holding the jaw slightly elevatedabove the stationary jaw to prevent the teeth thereof from engaging withthe teeth of the stationary handle. It will of course be understood, andas is clearly illustrated 26. The spring 25 is of a 17 has pivotallycon- 1 the teeth of the pivotal handle are reversed from the slot of theteeth of the stationary handle, whereby when the handles are clampedtogether, the teeth of the movable handle will fit tightly between theteeth of the stationary handle.

In briefly stating the operation of this invention it is to be statedthat the movable jaw is properly adjusted with respect to the fixed jawby grasping the lugs 18. After this operation, the movable handle 19 isde pressed against the action of the spring to force its toothed surfacein engagement with the toothed surface of the stationary handle, forpreventing any accidental slipping of the wrench upon the article to beturned. Should it be desired however, to positively retain the jaw in afixed adjustment on the shank 6, such is accomplished by tightening thethumb screw 29.

From the foregoing description, taken in connection with theaccompanying drawing, the advantages of construction and of the methodof operation will be readily apparent to those skilled in the art towhich the invention relates, and while I have described the principlesof operation of the device together with the device which I new considerto be the best embodiment thereof, I desire to have it understood thatthe device shown is merely illustrative and that such advantages may bemade when desired as are within the scope of the claims appended hereto.

Copies of this patent may be obtained for thereof, the protrudingportion of the spring adapted to engage with the recess of the handlesubstantially as and for the purpose specified.

2. A wrench comprising a shank having a fixed aw, a movable jaw slidablymounted upon said shank, a handle pivotally connected with the movablejaw, a handle fixedly secured to the shank of the fixed jaw and providedwith an elongated opening, the shank of the fixed jaw having an upwardlybeveled portion adapted to engage in the. elongated opening of the lastmentioned handle, the bottom wall forming the opening being inclined andadapted to be engaged by the beveled portion of the shank of the fixedjaw for the purpose specified.

ln'testimony whereof I aflix my signature in presence of two witnesses.

RICHARD J. SALES.
